Not sure if this is the correct spot to post this, but I am seeking info from anyone who might have experience with orange line trailers. Getting a package deal soon from a local dealer which includes the TH70 trailer. The trailers aren’t expected in for a month so I was using this time to get ready to haul it home when the day comes. I was looking into brake controllers and called the dealer to see if they offered any. They said that as long as I had a 7 pin connector on my hitch (I do), that an on board brake controller was not needed. I took that at face value for a day but it kept bugging me because I had never heard of such a thing. I called back, spoke with an actual salesman (first conversation was with a parts guy) and he said the same thing. The brakes were self adjusting and didn’t require an on board controller to work as long as you had a 7 pin instead of a 4 pin. Anyone have personal experience with these trailers and able to confirm? Thanks for any help.
